Emma and Daniel Millar knew their baby would be on the larger side - but didn't expect to welcome a 5.88kg bundle of joy this week. The average birth weight of babies in Australia is 3.3kg - or 7.2lb on the old scale. So Remi Frances Millar - at 12.9lb - is certainly above average. The healthy bub came into the world at Wollongong Hospital on Monday, at 38 weeks and two days, via emergency caesarean. Ms Millar, 27, said her size was a surprise. "She's like a mini sumo wrestler," she said with a laugh. "I did expect to have a larger baby as I had gestational diabetes but not this big. "At 35 weeks an ultrasound revealed she was about 4kg but we didn't think she'd grow that much more." It shouldn't have come as too much of a shock to the Mount Warrigal couple, whose daughter Willow - now two - weighed 5.5kg at birth. They also have a four-year-old son Ace, who was 3.8kg at birth. "Willow was a big girl too," said Mr Millar, "but she's stick thin now so it evens itself out. "Our other children just adore Remi, who is really healthy and content and just thriving." According to the most recent NSW Mothers and Babies report, almost four out of 10 Australian babies weigh 3 to 3.5kg. Only 1.2 per cent weight over 4.5kg. In the Illawarra Shoalhaven Local Health District in 2017, there were 58 newborns (or 1.3 per cent of total births) weighing more than 4.5kg. But midwives at Wollongong Hospital this week couldn't remember a newborn tipping the scales at 5.88kg. "When I've walked around with her there's always a crowd of people - midwives, other new parents and visitors - around her, asking about her size because she's so much bigger than all the other newborns," Mr Millar said. "She's definitely making an impression." Ms Millar is recovering from her C-section, and not allowed to pick up anything bigger than, well her baby. "She's about the limit I've been told," she said. "I had an emergency caesarean with my son and after that elected to have caesars as it was safest for me and my babies. "It ended up being an emergency caesar again with Remi though because my waters broke early. "I don't think I could have handled a natural birth with her." On Thursday, the couple was packing up to take Remi home - with many items of clothing left unused. "We had many little outfits in size 0000 but she's actually a 00," Ms Millar said. "We only had one outfit that actually fitted her on Monday."
